Interesting (and very long) article about the history of this practice in both the Olympic body and other athletic organizations, and also some history on intersex female Olympians. It also does a good job of breaking down the many different intersex or atypical chromosomal states people can have, if you are unfamiliar:
The word “hermaphrodite” is considered stigmatizing, so physicians and advocates instead use the term “intersex” or refer to the condition as D.S.D., which stands for either a disorder or a difference of sex development. Estimates of the number of intersex people vary widely, ranging from one in 5,000 to one in 60, because experts dispute which of the myriad conditions to include and how to tally them accurately. Some intersex women, for instance, have XX chromosomes and ovaries, but because of a genetic quirk are born with ambiguous genitalia, neither male nor female. Others have XY chromosomes and undescended testes, but a mutation affecting a key enzyme makes them appear female at birth; they’re raised as girls, though at puberty, rising testosterone levels spur a deeper voice, an elongated clitoris and increased muscle mass. Still other intersex women have XY chromosomes and internal testes but appear female their whole lives, developing rounded hips and breasts, because their cells are insensitive to testosterone. They, like others, may never know their sex development was unusual, unless they’re tested for infertility — or to compete in world-class sports.
Some history tidbits:
Amid complaints about the genital checks, the I.A.A.F. and the I.O.C. introduced a new “gender verification” strategy in the late ’60s: a chromosome test. Officials considered that a more dignified, objective way to root out not only impostors but also intersex athletes, who, Olympic officials said, needed to be barred to ensure fair play. Ewa Klobukowska, a Polish sprinter, was among the first to be ousted because of that test; she was reportedly found to have both XX and XXY chromosomes. An editorial in the I.O.C. magazine in 1968 insisted the chromosome test “indicates quite definitely the sex of a person,” but many geneticists and endocrinologists disagreed, pointing out that sex was determined by a confluence of genetic, hormonal and physiological factors, not any one alone.
The night before the race, a team official told her that her chromosome test results were abnormal. A more detailed investigation showed that although the outside of her body was fully female, Patiño had XY chromosomes and internal testes. But because of a genetic mutation, her cells completely resisted the testosterone she produced, so her body actually had access to less testosterone than a typical woman. Just before the Spanish national championships began, Spanish athletic officials told her she should feign an injury and withdraw from athletics permanently and without fuss. She refused. Instead, she ran the 60-meter hurdles and won, at which point someone leaked her test results to the press. Patiño was thrown off the national team, expelled from the athletes’ residence and denied her scholarship. Her boyfriend and many friends and fellow athletes abandoned her. Her medals and records were revoked.
Patiño became the first athlete to formally protest the chromosome test and to argue that disqualification was unjustified. After nearly three years, the I.A.A.F. agreed that without being able to use testosterone, her body had no advantage, and it reinstated Patiño. But by then, her hopes for making the Olympics were dashed.
Fellow athletes, the press and commenters on social media scrutinized Semenya’s body and made much of her supposed gender transgressions: her muscular physique, her deep voice, her flexed-biceps pose, her unshaved armpits, the long shorts she ran in instead of bikini shorts, in addition to her extraordinary speed. A story on Time magazine’s website was headlined “Could This Women’s World Champ Be a Man?” One of Semenya’s competitors, Elisa Cusma of Italy, who came in sixth, said: “These kind of people should not run with us. For me, she is not a woman. She is a man.” The Russian star runner Mariya Savinova reportedly sneered, “Just look at her.” (The World Anti-Doping Agency would later accuse Savinova of using performance-enhancing drugs and recommend a lifetime ban.) The I.A.A.F. general secretary, Pierre Weiss, said of Semenya, “She is a woman, but maybe not 100 percent.” Unlike India, South Africa filed a human rights complaint with the United Nations arguing that the I.A.A.F.’s testing of Semenya was “both sexist and racist.” Semenya herself would later write in a statement, “I have been subjected to unwarranted and invasive scrutiny of the most intimate and private details of my being.”
After nearly a year of negotiations (the details of which are not public) the I.A.A.F. cleared Semenya to run in 2010, and she went on to win the silver medal in the 2012 Olympics. She will be running in Rio.
The I.A.A.F. maintained it was obliged to protect female athletes from having “to compete against athletes with hormone-related performance advantages commonly associated with men.” In 2011, the association announced that it would abandon all references to “gender verification” or “gender policy.” Instead, it would institute a test for “hyperandrogenism” (high testosterone) when there are “reasonable grounds for believing” that a woman may have the condition. Women whose testosterone level was “within the male range” would be barred. There were two exceptions: If a woman like Maria Patiño was resistant to testosterone’s effects — or if a woman reduced her testosterone. This entails having her undescended testes surgically removed or taking hormone-suppressing drugs.
The framework for the article is the story of Dutee Chand, who has successfully caused a stay of the current International Association of Athletics (I.A.A.F.) policy until the I.A.A.F. can provide sufficient scientific evidence that the testosterone advantage of intersex women is identical to the advantage of male athletes over female athletes. The I.A.A.F. has until July 2017 to submit evidence, and the I.O.C. (the Olympic body) has said it will not move forward on any specific sex/gender policies until the case is settled.
At 16, she also became a national champion in the under-18 category, winning the 100 meters in 11.8 seconds. The next year, she won gold in the 100 meters and the 200 meters. In June 2014, she won gold yet again at the Asian championships in Taipei.
Not long after that, she received the call to go to Delhi and was tested. After her results came in, officials told her she could return to the national team only if she reduced her testosterone level — and that she wouldn’t be allowed to compete for a year. The particulars of her results were not made public, but the media learned, and announced, that Chand had “failed” a “gender test” and wasn’t a “normal” woman. For days, Chand cried inconsolably and refused to eat or drink. “Some in the news were saying I was a boy, and some said that maybe I was a transsexual,” Chand told me. “I felt naked. I am a human being, but I felt I was an animal. I wondered how I would live with so much humiliation.”
Over four days in March 2015, a three-judge panel heard Chand’s appeal, as a total of 16 witnesses, including scientists, sports officials and athletes, testified.
Female athletes, intersex and not, wondered just how this case would affect their lives. At the hearing, Paula Radcliffe, the British runner who holds the women’s world record for the marathon, testified for the I.A.A.F., saying elevated testosterone levels “make the competition unequal in a way greater than simple natural talent and dedication.” She added, “The concern remains that their bodies respond in different, stronger ways to training and racing than women with normal testosterone levels, and that this renders the competition fundamentally unfair.”
Just what role testosterone plays in improving athletic performance is still being debated. At the hearing, both sides agreed that synthetic testosterone — doping with anabolic steroids — does ramp up performance, helping male and female athletes jump higher and run faster. But they disagreed vehemently about whether the body’s own testosterone has the same effect.
I.A.A.F. witnesses testified that logic suggests that natural testosterone is likely to work the way its synthetic twin does. They pointed to decades of I.A.A.F. and I.O.C. testing showing that a disproportionate number of elite female athletes, particularly in track and field, have XY chromosomes; by their estimates, the presence of the Y chromosome in this group is more than 140 times higher than it is among the general female population. Surely, witnesses for the I.A.A.F. argued, that overrepresentation indicated that natural testosterone has an outsize influence on athletic prowess.
Chand’s witnesses countered that even if natural testosterone turns out to play a role in improving performance, testosterone alone can’t explain the overrepresentation of intersex elite athletes; after all, many of those XY female athletes had low testosterone or had cells that lacked androgen receptors. At the Atlanta Games in 1996, one of the few times the I.O.C. allowed detailed intersex-related data to be released, seven of the eight women who were found to have a Y chromosome turned out to be androgen insensitive: Their bodies couldn’t use the testosterone they made. Some geneticists speculate that the overrepresentation might be because of a gene on the Y chromosome that increases stature; height is clearly beneficial in several sports, though that certainly isn’t a factor for Chand.
In fact, the I.A.A.F.’s own witnesses estimated the performance advantage of women with high testosterone to be between 1 and 3 percent, and the court played down the 3 percent figure, because it was based on limited, unpublished data.
Chand’s witnesses also pointed out that researchers had identified more than 200 biological abnormalities that offer specific competitive advantages, among them increased aerobic capacity, resistance to fatigue, exceptionally long limbs, flexible joints, large hands and feet and increased numbers of fast-twitch muscle fibers — all of which make the idea of a level playing field illusory, and not one of which is regulated if it is innate.
But the I.A.A.F. argued that testosterone is different from other factors, because it is responsible for the performance gap between the sexes. That gap is the very reason sports is divided by sex, the I.A.A.F. says, so regulating testosterone is therefore justified.
Stéphane Bermon, an I.A.A.F. witness who took part in the efforts to identify females with high testosterone, acknowledged that doping was a significant threat to fairness but said that didn’t negate the need to also regulate the participation of women with naturally high testosterone who may have an advantage. He offered an analogy: “Air pollution, like tobacco smoking, contributes to lung cancer, but one should never have to choose between these two before implementing prevention measures,” he wrote in an email. “As a governing body, I.A.A.F. has to do its best to ensure a level playing field. ... These two topics are different but can lead to the same consequence, which is the impossibility for a dedicated athlete to compete and succeed against an opponent who benefits from an unfair advantage.”
Last July, the Court of Arbitration for Sport issued its ruling in Dutee Chand’s case. The three-judge panel concluded that although natural testosterone may play some role in athleticism, just what that role is, and how influential it is, remains unknown. As a result, the judges said that the I.A.A.F.’s policy was not justified by current scientific research: “While the evidence indicates that higher levels of naturally occurring testosterone may increase athletic performance, the Panel is not satisfied that the degree of that advantage is more significant than the advantage derived from the numerous other variables which the parties acknowledge also affect female athletic performance: for example, nutrition, access to specialist training facilities and coaching and other genetic and biological variations.”
The judges concluded that requiring women like Chand to change their bodies in order to compete was unjustifiably discriminatory. The panel suspended the policy until July 2017 to give the I.A.A.F. time to prove that the degree of competitive advantage conferred by naturally high testosterone in women was comparable to men’s advantage. If the I.A.A.F. doesn’t supply that evidence, the court said, the regulation “shall be declared void.” It was the first time the court had ever overruled a sport-governing body’s entire policy.
On June 25, Dutee Chand qualified for the Rio Olympics, running the 100 meters in 11.30 seconds in Almaty, Kazakhstan, and breaking a national record for India. Later that day, she posted an even faster time of 11.24 seconds. She will be the first Indian woman to run the 100 meters in the Olympics since 1980.
It's probably a little difficult to understand the entire article from just highlights, so I recommend you read it in full. I just picked out the parts I found interesting. There is also a section about policies regarding trans athletes at the end.
Bar me from Olympic games if old.
